Cossington Smith said of her painting Interior in yellow: ‘The subject took me very much. It is a room with a wardrobe and a bed and carpet but the chief thing to me was the yellow walls…the whole thing is meant to express an interior with light…the sunlight did not come in in a definite way but the whole room seemed to be full of light, which is what I want to do more than the actual sunlight. I feel that even the shadows are a subdued light and they must have light in them as well as the light parts.’ (Interview with Hazel de Berg, 1965, National Library of Australia)
